DOOR.

Application filed May 10,

In the operation of hospitals it is desirable to leave aja-r the doorsto rooms in which there are patients so that nurses and attendants mayquietly pass through and interior arrangements may be such that thepatients will not be in full sight of persons who may be passing alongthe corridor but for the view afforded through the space between thedoor and jamb on the hinge side of the door as doors are ordinarilyhinged.

The object of this invention is to provide a construction of door jamb,door and hinge which will not leave an opening between the door and ambon the hinge side of the door when the door is a-jar.

In the accompanying two sheets of drawings which form a part of thisdescription,

Figure 1 is a horizontal section through a door jamb and dooren'ibodying this invention. on the line I-I of Figs. 3 and a.

Fig. 2 is a similar section through the hinge on the line II-II of Figs.3 and l.

Fig. 3 is an elevation of the door jamb to which the door is hinged withthe door open.

Fig. 1 is an elevation of the same with the door jamb broken away on theline 1V IV of Fig. 8.

Fig. 5 is a perspective of the hinge.

Fig. 6 is a perspective view of a door embodying this invention mountedin position.

The door opening has the usual door jambs 10, 10 and a head piece 11. Asshown these parts are of pressed sheet metal but this material is notessential. The door jamb to which'the door is hinged has a corner bead12 with a cylindrical surface of about one-half of a cylinder. This headis also provided for uniformity of appearance on the other door jamb andon the head piece. The head is interrupted 'or has gaps at the pointswhere the hinges are to be located and the door jamb is cut awayrecessed or mortised at these points to provide space for the hinges.With the pressed sheet metal construction a reinforcement bar 13 is setbehind the jamb at the recessed points and held in place by riveting orspot welding. Each hinge consists of a center pin 14, a plate 15 whichis attached by screws to the reinforcement bar and aslip plate 16 whichslides into a pocket formed behind a plate 17 which is attached to theedge of the door 18. A rivet 19 passes through the pocket and engages anotch 20 in the upper 1926. Serial No. 108,063.

edge of the slip plate. The hinge is positioned and attached to the anddoor so that the axis of its center pin will coincide with the axis ofthe bead and the edge of the door will lie in close proximity to thebead and remain so as the door is swung open.

Doors sometimes require to be removed and the usual method of detachingby withdrawing the center pins from the hinges is not possible with thisconstruction. Unscrewing the hinges is'too slow. Therefore the slipplate connection is provided. \Vhen the door is open, it is liftedslightly to disengage the rivets through the pockets from the notches inthe slip plates and the door can then be lifted away. It will be notedthat by reason of the location of the pockets at the edge of the doorand parallel therewith, the weight of the door does not come to anyextent on the rivets through the pockets which engage the slip plate ofthe hi gges. Also by reason of this location of the pockets they are notin a conspicuous place and are entirely concealed when the door isclosed.

I claim:

1. The combination of a door jamb provided with a corner bead having acylindrical surface, the bead having gaps to receive hinges each hingebeing set with the axis of its pin in line with the axis of the bead,and a door carried by the hinge with an edge in close proximity to thebead of the door jamb. v

2. The combination of a door jamb provided with a corner bead having acylindrical surface, the bead having gaps to receive hinges each hingebeing set with the axis of its pin in line with the axis of the bead,one plate of thehinge being attached to the door jamb, and a doorprovided. with pockets at its edge to receive the other plates of thehinges.

8. The combination of a door jamb, hinges, one plate of each beingattached to the door jamb, and a door provided with pockets at its edgeand parallel therewith to receive the other plates of the hinges, eachpocket having a plate which overlies the hinge plate whereby the hingeplate is adapted to be held without the use of removable fasteningmeans. 1
